SPECIFICATION forming part of Letters Patent No. 247,908,-dated October 4, 1881.

application nieu January 2s, 1ers.

To all whom ,it may concern: f

Be it known that I, BENJAMIN R. HAWLEY, of Hyde Park, in the county of Cook and State of Illinois, have invented certain Improvements in Cook-Stoves, of which the following is a specification.

In the accompanying drawings, Figure l is a side elevation of my improved stove with the oven in place. Fig. 2 is a central section.

io ofthe same. Fig. 3 is a plan view of the stove, and Fig. 4 a horizontal section thereof upon the line a: rr of Fig. 1. Fig. 5 is a front view. Fig. 6 is detached view of a part of the firepot.

Likelettersindicatelike parts wherever used in the several figures.

Referring to said drawings, A represents the vertical walls, B the bottom, and C the top, of my improved stove. The first of these is conzo structed of two shells,aa, one within the other, and withan air-space between, as at a. This air-space acts anon-conductor,and thus is retained within the heating-chamber much of the heat which otherwise would be given vout into the room and lost. The bottom, together with the ash-pit b and hearth b', are cast in one piece. Under an opening at the rear end of this bottom is attached the escape -flue b2. The top is provided with holes c c, one directly over the lire-pot and the other in the rear, with a removable bridge-piece, c, between, to permit the insertion of the ordinary wash-boiler.

At each side, and midway between the ends,

are overhanging or projecting shelves c2 c2,

3 5 which are useful when several articles or dishes are being cooked or Vwhen the direct action oi the tire is more intense than is desired for some parts of the cooking.

D is a plate covering the ash-pit, with the 4o exception ofthe opening therein over the grate andunder the fire-pot. .This plate is fitted in a groove in the bottom at the rear side thereof, and to it is affixed an upwardly-projectin g an ge, d, which connects with a similar iange upon the bottom, and forms a continuation thereof, the same giving form and abutment to the inner shell a.

The fire-pot is surrounded by a ring, d', (attached to the plate D,) which supports the sec- 5o tions or segments d2 thereof. These segments culiarities which adapt it to be used with this rest at their tops upon the top of the ring, and at their bottom are held in vposition by lugs or projections d3, extending from their backs to the ring, as will be fully understood from Figs. 2 and 6, the latter showing the back of 55 one of them. They are forked at their lower ends and provided with air-openings near the upper portions, as shown in the drawings. d4 is the grate, which turns upon pivots d5, one of which is flattened, and receives upon such flattened portion the pressure of a spring, d'3, whereby the grate is retained in a horizontal plane.

Just above the tire-pot is a fuel-feeding door, E, and in front of the ash-pit is also a door, E', provided with draft-openings e, made regulable by any of the ordinary methods of con-- structing such parts of stoves. f

F is a removable oven, having certain pe- 7o stove, and it may be made appart of the stove, if desired. It is provided at the bottom with a collar, f, which sets down into the rear opening in the stove-top. Midway across this collar, and extending up into the oven untilit meets the lining thereof, is a partition, j", depending from which is an apron,f2, which may be attached by a hinge-joint, and which, when the oven is placed upon the stove, drops down into the heating-chamber ofthe stove, as clearly shown in Fig. 2. The effect of this apron is to cause the greater part ofthe air and products of combustion to enter the oven and pass through the flue surrounding the same, in the manner ,indicated by the arrows in said figure; butinas mueh as the agron does not completely ll the space of the chamber, so as to cut oft' all direct escape for the gases, it will be found that the heavier portions thereof will still follow their natural course and pass downward to the exit in the manner indicated by other arrows in said figure. That powrtion of the oven directly over the stove-opening and in front of the partition, being exposed to very great heat, is preferably covered upon the in- 95 side with a plate, f3, as shown in Fig. 2, thereby doubling the lining at the point exposed to the greatest heat. The usual shelving, f4, may also be placed within.

The oven is provided with an interior lining7 loo f5, which may, if desired, be made removable for purposes 4of repair. It' made removable, it may be taken out through the door-opening by simply loosening` the screwfG in the back, by which it is held, and detaching the depending apron. The passage for heat is neXt outside this lining. The exterior of the oven, or that part thereof surrounding the Hue, I prefer to make with a dead-air space, f7, both to economize the heat and to keep the kitchen cool. The door and hack should for similar reasons be constructed with double walls.

The body ot' the stove I make oval or oblong, as shown in the drawings. For a small and economical form this will be found especially advantageous.

The plate or shield f3 is lnade of the peculiar construction shown in the drawings, in order to deliect the heat toward the farther side of the oven, which would naturally be the cooler side, and for this purpose openings are made in that part thereof which stands vertically.

In stoves of this hind the tile will be found to be regulated to some extent automaticallythat is to say, when the heat is not absorbed by the cooking as rapidly as it is produced the force of the expanded air within the chamber checks the draft, and the combustion is retarded until the checking force is withdrawn.

I am aware that stoves have been constructed with non-conducting vertical walls.

I am also aware that stoves and furnaces have been made wherein the outlet-flue debouched from the heating-chamber at a point below the top of the [ire-pot.

I claim as newl. The combination, with the cookstove wherein the products of combustion are discharged into an open-chamber, ot' an oven having a ilue ruiming over the same andan apron placed at the nue-opening and depending within but not reaching to the bottom of Said chamber, so as to deect the products of combustion and heated air into the flue, substantially as specified.

2. The oven provided with the dedectingapron, and wherein is combined with said apron and with the lininga bent piece,f3, placed upon the inside, as shown, whereby the heatrays from that portion of the lining receiving the greatest amount of heat are turned toward the cooler side of the oven and burning at that point is prevented.

3. rEhe oven constructed with the removable lining, held in place by screws or bolts, and removable through the door opening, and provided with the deiiecting-apron, substantially as set forth.
